Show info: I will be gone from home from about January 25th until about February 15th. I will be at my usual show location: Ramada Limited, room 134. This is at St Marys and the interstate (next to Denny's) - just 1/4 mile or so due West of Inn Suites (Now called Hotel Tucson City Center - where many of the other meteorite dealers are). My room is about mid-way down the length of the motel (right next to the walk through actually) on the west- side of the building (on the parking lot side - and there is often parking available right in front of my room). I should be open the afternoon of January 28th through the afternoon of February 11th. I will be open every day in between - generally from 10AM until - ? (usually at least 7pm if I am going out to eat and often until 10pm or so other nights). Hope to see you there. Bring lots of cash and buy. Thanks!

Dear Collectors,
Happy New Year! Here is the e-mail version of my "what's new" mailed list. Do make note of the "gone" dates below and try to contact me before January 20th if you want anything here (this will allow for packing/ shipping time and such).

APACHE JUNCTION, Arizona: Medium octahedrite (IIIAB). Found before 2005. Tkw = 25 kilograms.
I just got a few (5) pieces of this really nice new meteorite. It was purchased by Dr.Carelton Moore from a seller who claimed to have found it near the intersection of McKellips Rd and Ironwood Dr in the city of Apache Junction years earlier. Dr Moore ended up purchasing this iron, despite having the fear that it might really be a "transported" Canyon Diablo. Later cutting and etching revealed a vibrant medium octahedrite structure and quickly removed all doubt concerning its new find status. The main mass is bound for the ASU collection at this point and only 2 more pieces are available to me beyond these listed (so don't wait if you want a piece of this).
1) Etched slices:
a) 19.3 grams - 33mm x 18mm x 4mm - $135
b) 53.5 grams - 65mm x 22mm x 4mm - $360
c) 102.7 grams - 100mm x 64mm x 3mm - $650 – complete slice with 10mm+ natural hole.
d) 208.9 grams - 120mm x 80mm x 4mm - $1200 – complete slice.

GOLD BASIN, Arizona: (L4). Found November 1995. Tkw = 127+ kilograms.
This is the famous material that was often (in the early days) found perched next to shallow holes where a gold prospector left it as a "hot rock" in disappointment that it was not a gold nugget. These pieces came from a rare large piece of this meteorite. I only learned after I cut it up that this was quite unusual for its size. I guess this means though, that now collectors have the chance to own an unusually large slice of this famous meteorite. These pieces are quite fresh and show a good number of sometimes large chondrules in a light tan to brown matrix (I sent off a piece for a quick micro-probe check to be sure that this was not Arizona's first LL5, as this does look quite similar to Tuxtuac in many respects).
1) Slices:
a) 6.1 grams - 30mm x 15mm x 4mm - $10
b) 11.8 grams - 35mm x 30mm x 4mm - $18
c) 25.8 grams - 40mm x 40mm x 4mm - $39
d) 54.7 grams - 70mm x 67mm x 4mm - $80
e) 126.0 grams - 100mm x 70mm x 5mm - $190 - nice complete slice.
2) End piece:
a) 260.4 grams - 100mm x 60mm x 16mm - $325

NWA (7044): Ordinary chondrite (H6). Found before September 2011. Tkw = 1443.4 grams.
This had a small broken corner that showed a very crystalline texture to it (reminding me of a "primitive achondrite"). This was not cheap, but the chance that this something interesting tied with the fact that is pretty much perfectly oriented led me to buying the piece. When I shaved off a slice, it showed a fair amount of really fine metal grains and looked virtually identical to a small piece of a weathered EL6 I had (Yilmia, Australia). I rushed the sample off to get it looked at and the initial reaction was that this was indeed an EL chondrite. Unfortunately, the full work-up showed it to be an H. Thankfully I did not start cutting this up (slices of a W2 enstatite chondrite would be very good for me right now). Anyway, this has been left as a nice shield-shaped oriented individual.
1411.5 gram oriented individual – 125mm x 100mm x 55mm - $1500.00

MOAPA VALLEY, Nevada: Carbonaceous chondrite (CM1). Found September 2004, Tkw = 698.8 grams.
This may be the rarest, by type, meteorite I have ever offered. There is only around 850 grams of CM1 material currently known in the world (and of that, only one other from outside of Antarctica – the 19gram NWA (4765)). This is like the more famous CM2 material (Murchison probably being the most famous example), but had MUCH more water flow through it on its parent body. This looks pretty much like dark (nearly black) carbon (charcoal brickette like) on fresh cut or broken surfaces. All of the minerals in this have been altered to secondary phases and there are no chondrules present (just some rounded serpentine and sulfur rich inclusions). I have only 7 grams of this and there are no remaining pieces available to me. If the 4g I had offered on an e-mail offering a couple years ago is any guide, this won't last long, so contact me quickly if you want some of this stuff.
1) Fragments/ cut fragments: all in membrane boxes.
a) .072 grams - 5mm x 3mm x 2mm - $70
b) .132 grams - 7mm x 5mm x 3mm - $125
c) .226 grams - 6mm x 5mm x 4mm - $210 – cut fragment.
d) .410 grams – 13mm x 9mm x 3mm - $370
e) .81 grams - 10mm x 8mm x 6mm - $700
f) 1.21 grams - 15mm x 12mm x 5mm - $1030 – small area of crust.
g) 1.72 grams - 16mm x 11mm x 7mm - $1450 – end piece, nice crust on one edge.

BLUE SALT, Carlsbad, New Mexico.
I picked up some samples of this while at the Socorro Mineral Symposium and though that some collectors might like a piece as similar blue salt crystals have been found in some H-chondrites (Zag and Monahans (1998)). These crystals that were found in these meteorites show that water flowed through parts of even the H parent body (where as it was considered to be that water was likely present on only a few carbonaceous parent bodies). Like the Halite (sodium chloride – NaCl) in the meteorites, this halite has turned violet/blue from radiation damage. Radiation causes crystal lattice distortions and the release of sodium metal in the structure. This causes all but the blue and violet wavelengths of light to be absorbed (turning the salt violet and blue in color). The salt in the meteorites was exposed to cosmic radiation. These samples were exposed to radiation from chunks of the mineral Sylvite (potassium chloride or KCl) that has some radioactive potassium in its structure that was deposited near this salt layer.
1) Fragments
a) roughly 7 to 10 grams (about 18mm x 15mm x 15mm) - $10
b) roughly 20 grams (about 28mm x 23mm x 18mm) - $20
c) roughly 50 grams (about 35mm x 30mm x 23mm) - $30

Please include postage: a couple dollars on small U.S. orders and $10 on large items for first class (insurance is extra, if desired). On small overseas orders, $3 to $5 is generally plenty (I'll have to custom figure the rate for large items). Registration is also recommended on more valuable overseas shipments - an extra $12.00.
If you are sending a fax, simply begin transmitting when my line is answered. My fax will turn on automatically to receive (or I will start it if I answer) when you begin transmitting.
